Hi
I'm having a bit of problem how to add to this sketch to convert analog pins to read as digital, so after looking around managed to figure out sketch that works and I can have 14 buttons on sketch below but not sure what and where I have to write to change the analog pins to work as the rest of digital, A0-A5 if someone could help please.
Thank you

thanks for link but still can't get it to work 
Sounds like a wiring problem.
Start with 1 switch.
Pin0 and pin1 can't be used for buttons, because those pins are already used by the USB<>Serial chip.
Pin13, with an unbuffered LED, could be problematic too when used as input. Don't use.
Answer #1 on the link from post#1 is wrong for a Leonardo.
Leonardo pin numbering for the analogue pins A0-A5 seems to be 18-23, not 14-19.
Could use a pin array for the button pins. See example sketch.
Leo..
const byte buttonPins[] = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 18, 19, 20};
const byte buttonCount = 14;
void setup() {
for (int i = 0; i < buttonCount; i++) pinMode(buttonPins[i], INPUT_PULLUP);
}
void loop() {
}
Hi,
Welcome to the forum.
Please read the post at the start of any forum , entitled "How to use this Forum".
OR
http://forum.arduino.cc/index.php/topic,148850.0.html.
Then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
Thanks... Tom...

OP is using a Leonardo.
As OP does not seem to be using Serial1, there should not be an issue.
I do apologise for not posting the code correctly, I am not experience in using much of the arduino range a specially code part, most of my projects is from video and try and error, this code has been used for something else and it works for me from Pin 0 - 13, now this give me 14 digital inputs, for my new project I have spare leonardo board in drawer so wanted to utilize this but need 19 inputs, I know is possible to use the A0-A5 analog pins to use it as digital input for switches ect. (toggle/rotary), maybe a bit cheeky of me asking what I should and where write it to have this working but if I don't ask I won't know 
as for wiring there isn't much, lets say there will be 19 toggle switches, on/off nothing fancy, I know there are other boards that would be lot easier for me to use but this is just laying around so with your help if I can get this working would be great.
Also only using 1 switch to try the individual pins, one at the time
#include <Joystick.h>
Joystick_ Joystick;
int led = 13;
void setup() {
// Initialize Button Pins
pinMode(0, INPUT_PULLUP);
pinMode(1, INPUT_PULLUP);
pinMode(2, INPUT_PULLUP);
pinMode(3, INPUT_PULLUP);
pinMode(4, INPUT_PULLUP);
pinMode(5, INPUT_PULLUP);
pinMode(6, INPUT_PULLUP);
pinMode(7, INPUT_PULLUP);
pinMode(8, INPUT_PULLUP);
pinMode(9, INPUT_PULLUP);
pinMode(10, INPUT_PULLUP);
pinMode(11, INPUT_PULLUP);
pinMode(12, INPUT_PULLUP);
pinMode(13, INPUT_PULLUP);
// Initialize Joystick Library
Joystick.begin();
}
// Constant that maps the physical pin to the joystick button.
const int pinToButtonMap = 0;
// Last state of the button
int lastButtonState[14] = {0,0,0,0,0,0,0,0,0,0,0,0,0,0};
void loop() {
// Read pin values
for (int index = 0; index < 14; index++)
{
int currentButtonState = !digitalRead(index + pinToButtonMap);
if (currentButtonState != lastButtonState[index])
{
Joystick.setButton(index, currentButtonState);
lastButtonState[index] = currentButtonState;
}
}
delay(50);
}
